简要总结
Background: Complete overdenture manufacturing has been greatly developed using computer-aided designing and computer-aided manufacturing (CAD-CAM) technology.
Material and method: 15 completely edentulous patients, divided into two groups, received two implants in the mandibular canine area with ball attachment. The first group received a CAD/CAM-milled mandibular overdenture and a maxillary acrylic conventional complete denture, while the second group received a 3D-printed mandibular overdenture and a maxillary acrylic complete denture. Peri-implant soft tissue and denture adaptation were evaluated using clinical parameters
详细描述
Background: In recent years, complete overdenture manufacturing has been greatly developed using computer-aided designing and computer-aided manufacturing (CAD-CAM) technology. This clinical study compared the soft tissue health between CAD/CAM-milled and 3D-printed implants that retained complete overdentures.
Material and method: 15 completely edentulous patients, divided into two groups, received two implants in the mandibular canine area with ball attachment. The first group received a CAD/CAM-milled mandibular overdenture and a maxillary acrylic conventional complete denture, while the second group received a 3D-printed mandibular overdenture and a maxillary acrylic complete denture. Peri-implant soft tissue was evaluated using clinical parameters including the gingival index, plaque index, bleeding index, and probing depth at the time of mandibular complete overdenture insertion (T0), six months (T6), and twelve months (T12) of denture use.
